Surface patterns in drying films of silica colloidal dispersions
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
We report an experimental study on the drying of silica colloidal dispersions. Here we focus on a surface instability occurring in a drying paste phase before crack formation which…
Structural anisotropy of directionally dried colloids
François Boulogne, Ludovic Pauchard, Frédérique Giorgiutti-Dauphiné +6
Aqueous colloidal dispersions of silica particles become anisotropic when they are dried through evaporation. This anisotropy is generated by a uniaxial strain of the liquid disper…
How to reduce the crack density in drying colloidal material?
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
The drying of a colloidal dispersion can result in a gel phase defined as a porous matrix saturated in solvent. During the drying process, high mechanical stresses are generated. W…
The buckling and invagination process during consolidation of colloidal droplets
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
Drying a droplet of colloidal dispersion can result in complex pattern formation due to both development and deformation of a skin at the drop surface. The present study focus on t…
Effect of a non-volatile cosolvent on crack pattern induced by desiccation of a colloidal gel
François Boulogne, Ludovic Pauchard, Frédérique Giorgiutti-Dauphiné
Consolidation of colloidal gels results in enormous stresses that are usually released in the formation of undesirable cracks. The capacity of a gel network to crack during drying…
